I agree with the other posters that the present site doesn´t offer as much to see as one might expect, which is only understandable if you know what the Romans did to Carthage (completely razed the city, killed or enslaved its people and poured salt on the ground so that nothing would ever grow there again). However, a Roman city did eventually form there, and its ruins are still impressive, especially the baths. You mustn´t take pictures of the Tunisian President´s palace nearby, so beware! The guards may take your camera away! Anyway, besides the very few genuinely Carthaginian remnants and the great view of the sea, the most important thing is just to go there and to know that you´re standing on the site of one of the world´s great civilizations - one that brought mighty Rome almost to its feet.
